A Collective Subconscious (ACS) is an instrumental cerebral post-rock band from Portland, Oregon that formed in the winter of 2012. Over the next year the band worked extensively on material for live shows and what would become their debut album, titled "Entheogens." After 4 years of playing local and regional shows, ACS would release their highly anticipated second EP "Sanskara", in 2017.

Having been compared to musical acts such as Mogwai, Godspeed You Black Emperor!, Jakob, Tool, and Deftones, A Collective Subconscious bring their own unique style of vast, atmospheric, heavy, and melodic instrumental cerebral post-rock. On stage, ACS delivers an intriguing array of sound and live video that's complimented with themes of social commentary, nature, industrialism, and the abstract.
